This guide connects a production HyperX project to a Unity client. Unity 2021 LTS or later with .NET Standard 2.1 compatibility is recommended.

​
1. Download the SDK DLL

Download HyperX.netstandard2.1.dll.

​
2. Add It to Unity

Place the DLL under Assets/Plugins. In Unity Player Settings, set Api Compatibility Level to .NET Standard 2.1 or later.

​
3. Copy the Project Code

Open the project in Console and copy its project code from the URL or project settings.

​
4. Initialize and Create a Guest User

Attach this script to an empty GameObject and replace PROJECT_CODE. 
using UnityEngine;

public class HyperXBootstrap : MonoBehaviour
{
    async void Start()
    {
        await HyperX.Core.Init("PROJECT_CODE");

        var player = await HyperX.Core.Users.StartGuestSession(
            authenticationToken: SystemInfo.deviceUniqueIdentifier,
            country: "US",
            language: "en"
        );

        var me = await player.Me();
        Debug.Log($"HyperX user: {me.Id}, name: {me.Name}");
    }
}
Run the scene, then confirm the created user on the Console Users page. StartGuestSession returns a player session that carries the access token. After that, authenticated calls such as user data, ranking, coupons, notifications, and chat can use player.PutUserDataJson(...), player.SubmitRankingJson(...), and player.Notifications(...) without passing session.AccessToken through every call.
